I have a kadet sr with a os 46 in it for my 8 year old sons training but i ran across a e-fligt apprentice trade for one of my small warbird scratch built airplanes and made the deal. I was very impressed yesterday when i took him out for a lesson with how the apprentice can float along at very slow flight and also land very slow. I will be training him on both ,but for easy fast trip to the field the apprentice is the way to go for me and him. I can charge 3 -3200 lipo packs at home and when one is dead i can throw it on a charge at the field and keep flying. Good luck with what ever you choose and try to find a club and instructer with a buddy box to help you learn on. After my 8 year old learns how to fly i will have to put my good planes up high in the basement where he cant reach them. lol joe
